Bayesian reasoning is just a tool that you use when you're dealing in situations of uncertainty. There's no, again, there's really no choice about it. If you collect enough data, good Bayesians will always converge on the same answers. Is there value in considering physical quantities other than momentum in the same light? Well, maybe. But physicists very often will take something they think is a constant and say, well, what if it's a variable?
Welcome to the October 2022 Ask Me Anything episode of Mindscape! These monthly excursions are funded by Patreon supporters (who are also the ones asking the questions). We take questions asked by Patreons, whittle them down to a more manageable number — based primarily on whether I have anything interesting to say about them, not whether the questions themselves are good — and sometimes group them together if they are about a similar topic. Enjoy!
